The specific embodiment
Embodiment 1, a kind of horizontal screw centrifuge automatic feed control device, and the feed pipe 3 in control device is connected with horizontal screw centrifuge charging aperture 9, referring to Fig. 1.
The utility model comprises feed tank 1, feed pipe 3, water supply pipe 4, feed pipe 3 two ends connect respectively feed tank 1 and horizontal screw centrifuge 2, charging control valve 7 is installed on feed pipe 3, water supply pipe 4 is connected with the centrifuge charging aperture 9 of horizontal screw centrifuge, the utility model also comprises flowmeter 8, control instrument 12, current detecting member 10, charging control valve 7, inlet regulating valve 5 and cleaning control valve 6, wherein, the motor of current detecting member 10 and horizontal screw centrifuge 2, control instrument 12, charging control valve 7, flowmeter 8, inlet regulating valve 5 and cleaning control valve 6 form control circuit by loop, water supply pipe 4 comprises two water supply pipe branch roads in parallel, two water supply pipe branch roads of this parallel connection all are connected with feed pipe 3, wherein on a branch road, be provided with inlet regulating valve 5, be provided with on another branch road and clean control valve 6, be provided with flowmeter 8 on feed pipe 3.
Feed tank 1 in the utility model is provided with filter screen 11 with the junction of feed pipe 3.Charging control valve 7, inlet regulating valve 5, cleaning control valve 6 are magnetic valve.Two branch roads of water supply pipe 4 are arranged on respectively the two ends of described feed pipe charging control valve 7.Be provided with two above stirring motors in feed tank 1.
In the course of work, flowmeter 8, for detection of the size of inlet amount, feeds back to the open degree that control instrument 12 is controlled charging control valve 7, regulates inlet amount.Current detecting member 10 is for detection of the size of the current of electric of horizontal screw centrifuge 11, and simultaneously, the size of current that current detecting member 10 detects feeds back to control instrument 12, and control instrument 12 is controlled the size of charging control valve 7 open degree and controlled inlet amount.
During charging, it is as follows that the charging regulating loop is controlled the course of work, and the material source in feed tank 1 is by feed pipe 3, enter horizontal screw centrifuge 2(centrifuge per hour treating capacity be 5-12m
3), the flow value that flowmeter 8 detects changes 0～20MA current signal or 0～5V voltage signal etc. into, feed back in control instrument 12, control instrument 12 is through computings, by the open degree of controlling charging control valve 7, controls flow (by flow-control at 5-12m3).The current value that current detecting member 10 detects simultaneously feeds back in control instrument 12 in the same way, control instrument 12 is compared and is determined the switching situation of each valve through computing and setting value, mainly peak load value and the centrifuge incoming flow value of current of electric, when motor current value reaches certain load, control instrument 12 will cut out charging control valve 7.
That is to say, as Fig. 2, in whole process, current detecting member 10 detects electric current, and flowmeter 8 detects flow, and testing result enters control instrument 12 and judged, when electric current reaches in limited time, regulates charging control valve 7 and reduces flow.When flow reaches in limited time, regulate charging control valve 7 and reduce flow.When flow reaches in limited time lower, regulate charging control valve 7 augmented flows.
If in equipment running process during the current of electric excess load, as Fig. 3, the signal transmitted according to current detecting member 10, control charging control valve 7 and reduce open degree and reduce inlet amounies.When flow lower than the setting value 5m3/ hour, current of electric is excess load still, start and clean regulating loop, control instrument 12 will control charging control valve 7 and cut out, and the cleaning control valve 6 on water supply pipe 4 is opened simultaneously, and horizontal screw centrifuge is rinsed, after current of electric stream recovers normally, control instrument 12 is controlled, and cleans control valve 6 and closes, and charging control valve 7 is slowly opened.
Under the state of the normal charging control valve 7 of current of electric in opening fully, inlet amount is lower than setting value 5m3/ hour, as Fig. 4, start anti-the cleaning and regulate control loop, control instrument 12 will control charging control valve 7 and cut out, inlet regulating valve 5 on water supply pipe 4 is opened simultaneously, the filter screen 11 that feed pipe 3 is connected to feed tank one end carries out backwash, and washing time can arbitrarily be set, and rinses inlet regulating valve 5 later and closes, charging control valve 7 is slowly opened, and continues to start fill process.
To one skilled in the art, can make other various corresponding changes and deformation according to above description scheme and design, and all these changes and deformation all should belong in the scope of the utility model claim protection.
